You're driving a cargo tank (bulk packaging) hauling a hazardous material. Under the bulk packaging marking rules, where and how must the identification number appear on the tank?

Question

Accepted Answer

On two opposite sides of the tank (or on each side and each end if the tank's capacity is 1,000 gallons/3,785 L or more), in black numerals — at least 100 mm (3.9 inches) tall on an orange panel, or at least 88 mm (3.5 inches) tall when shown directly on a placard — or on a white, square-on-point display if no placards are required

Answer

Anywhere visible on the tank, in any color, at any size, as long as the four-digit number is legible from a distance

Answer

Only on the shipping papers — bulk packagings themselves are exempt from displaying identification numbers

Answer

On a single placard on the rear of the tank only; side markings are optional for cargo tanks
